How scores are calculated
Materials (40%): How plastic-free the product is — raw materials, construction, and coatings.
Packaging (20%): Is the product packaged in plastic? Is it recyclable?
Transparency (20%): Does the brand disclose ingredients, sourcing, and manufacturing?
Durability (20%): How long does it last? Longer-lasting products reduce plastic waste over time.
This is a rating of this specific product only — not the company. Other products from this brand may score differently.

Personal care products are applied directly to skin for hours or days. The FDA does not require pre-market safety testing for cosmetic ingredients. Many conventional products contain synthetic fragrance (hiding phthalates), parabens, formaldehyde-releasing preservatives, and 1,4-dioxane.
Why We Rated It This Way
Neutrogena Hydro Boost contains PEG compounds that may be contaminated with 1,4-dioxane — a probable human carcinogen. Fragrance-free is a plus, but the synthetic polymer base is a concern for daily use.
